Debt Service Coverage Ratio (DSCR) Calculator

Example:

Annual Rental Income: 600000

Annual Operating Expenses: 150000

Annual Debt Payments: 300000

Net Operating Income: 600000 - 150000 = 450000

Expected Calculation: 450000 / 300000 Expected Result: 1.50


Debt Service Coverage Ratio (DSCR) Calculator

A rental property may generate good income, but one important question remains:

Is that income enough to comfortably cover the property's debt payments?

The Prozameen DSCR Calculator helps you compare the property's net operating income with its annual mortgage or loan payments.

What is DSCR?

DSCR stands for Debt Service Coverage Ratio.

It compares the income generated by a property with the amount required to service its debt.

In simple terms, it can help show how much income is available to cover annual loan payments.

How to Use the Calculator

Enter:

  • Annual Rental Income
  • Annual Operating Expenses
  • Annual Debt Payments

The calculator will estimate the property's DSCR.

DSCR Formula

DSCR = Net Operating Income ÷ Annual Debt Payments

Net Operating Income is:

Annual Rental Income - Annual Operating Expenses

Example

Suppose a rental property generates:

  • Annual Rental Income: 600,000
  • Annual Operating Expenses: 150,000
  • Annual Debt Payments: 300,000

Net Operating Income:

450,000

Estimated DSCR:

1.50

This means the property's estimated net operating income is 1.5 times its annual debt payments.

Understanding the Result

A DSCR of:

1.00

means estimated net operating income is equal to annual debt payments.

A result above 1.00 means estimated operating income is greater than the debt payments entered.

A result below 1.00 means estimated operating income is lower than the annual debt payments entered.

Lenders may use their own DSCR requirements, calculation methods and qualifying criteria.

Why Can DSCR Be Useful?

DSCR can help property owners and investors understand the relationship between rental income, operating costs and loan obligations.

It can also make it easier to compare financing scenarios before making further decisions.

Important Information

This calculator provides a simplified estimate.

Actual lender calculations may treat income, expenses, reserves, taxes and debt obligations differently.

The result does not determine whether a mortgage or investment loan will be approved.
